Abstract

The present application discloses a method, apparatus and computer equipment for recognizing roads from remote sensing images. A specific embodiment of the method includes: determining the pixel points belonging to the road in the remote sensing image to be identified; determining the direction information of the pixel points belonging to the road in the remote sensing image based on the pixel points belonging to the road in the remote sensing image; According to the direction information of the pixel points belonging to the road, the expansion operation is performed on the pixel points belonging to the road; the road is determined from the above remote sensing image according to the expansion operation result. This embodiment improves the road network connectivity of roads identified from remote sensing images.

Description

technical field [0001] The present application relates to the technical field of remote sensing, in particular to information extraction of remote sensing images, and in particular to a method, device and electronic equipment for identifying roads from remote sensing images. Background technique [0002] At present, with the rapid development of the economy, the ground objects, especially the roads, are expanding very rapidly. The update of maps, especially the update of road network, is of great significance in the fields of economic construction, military affairs, and earthquake relief. Data can be quickly obtained from satellite or aerial remote sensing images, shortening the map update cycle, and making it possible for people to collect data, process information, update data, and analyze data in real time. Therefore, high-resolution remote sensing images have become an increasingly important data source in the surveying and mapping industry. [0003] Remote sensing ima...
